A study published in Nature Medicine found that increasing omega-3 intake in mice reduced damaging vessel growth in the eye, a cause of retinopathy and blindness. Omega-3 supplementation is being tested in premature babies at risk for vision loss in a clinical trial.
Researchers found that increasing omega-3 fatty acids and decreasing omega-6 fatty acids in the diet can reduce retinopathy severity by suppressing inflammatory proteins. The study suggests that omega-3 fatty acids may act as protective factors in diseases affecting retinal blood vessels.
Delft scientists observe topotecan's effect on DNA molecule loops, revealing mechanism of TopoIB protein in cell division. They use magnetic spheres and magnets to manipulate a single DNA molecule, allowing them to study the enzyme's action live.
A University of Utah study reveals that temperature differences within Earth's crust and upper mantle explain about half of North America's elevation. Coastal cities, including New York City and Boston, would be underwater if not for the buoyant effect of heat on rock, with elevations ranging from 1,427 to 3,756 feet below sea level.
Spanish researchers found that pigs fed large quantities of raw potato starch had a healthier bowel and decreased levels of white blood cells. The study, published in Journal of the Science of Food and Agriculture, suggests a potential beneficial effect on overall immune system health.
A study of 2,785 college students found that over half with significant anxiety or depression symptoms didn't seek help, despite available resources. Socioeconomic background was a key predictor of seeking help, with poor students being more prone to symptoms and less likely to seek treatment.
